2. Description of Related Art

Heat exchangers are typically utilized to transfer heat from onesubstance to another substance, wherein energy is expended by extractingheat from a heat source and delivering it to another source. While heatexchangers are useful in transferring heat, there are disadvantagesand/or problems associated with heat exchangers which may make themundesirable for certain applications.

For instance, heat exchangers require costly components. Heat exchangersrequire materials that conduct heat efficiently, such as, copper, whichis more expensive than other types of metals, such as steel. Secondly,many heat exchangers utilize extensive lengths of fine tubing, which iscostly, and which is difficult to repair and/or replace. Lastly, foulingin tubing is a common problem associated in mass heat transfer, whereincontaminants may stick on the walls of the heat exchanger tubing,restricting flow of the fluid therewithin, thereby rendering the heatexchanger inoperable.

Heat exchangers may operate for many uses, but one of the most common isas part of heating and air conditioning units, which are utilized togenerate hot or cold air. Heat exchangers are utilized in airconditioning units, wherein the traditional air conditioning unitcomprises a compressor, a condenser, and an evaporator. The combinationof air flowing over the coils of the evaporator functions as a heatexchanger. Working fluid arrives at the compressor as a cool,low-pressure gas, wherein the compressor compresses the fluid, therebyincreasing the energy and temperature of molecules of the fluid. Thefluid leaves the compressor as a heated, high pressure gas and flowsinto the condenser, in which cooling of the molecules of the fluidoccurs, changing the fluid from a gas to a liquid that remains underhigh pressure. The liquid then travels into the evaporator through anarrow hole, wherein the liquid's pressure drops as it expands andbegins to evaporate into a gas. As the liquid evaporates, it requiresheat, and, thus, it extracts heat from the air outside flowing over andaround the evaporator, thereby cooling the air.

Heat exchangers are also utilized in heat pumps. A heat pump functionssimilarly to an air conditioner, but allows for heating and cooling ofair. The working fluid cycle is reversible and the heat exchangers canoperate as either condenser or evaporator.

While air conditioning units are capable of cooling air, there areproblems associated with air conditioning devices. Because they exchangeheat from air with the cool fluid, air conditioners comprise severalcomponents that are expensive. If the fluid ceases to flow because of anobstruction, the fluid may locally freeze within or after leaving theevaporator, thereby preventing newly cooled fluid from entering to beheated by the air flowing over and around the evaporator. In such event,while the air conditioner may run, it does not put out cool air.Additionally, air conditioners have a low average life expectancy ofonly ten to twelve years. Accordingly, various attempts have been madeto overcome the deficiencies of traditional air conditioners.

Similarly, while heat pumps are capable of heating and cooling air,there are problems associated with traditional heat pumps. For example,heat pumps utilized in Northern climates encounter special problems. Oneof the main difficulties is that northern climates require high heatingcapacities and less cooling capacities while conventional heat pumpshave nearly equal cooling and heating capacities. Another inherentproblem associated with heat pumps is that liquid refrigerants enter anddamage the compressor. Additionally, heat pumps have a low average lifeexpectancy of only eight to fifteen years. Accordingly, various attemptshave been made to overcome the deficiencies of traditional heat pumps.

For instance, one previous device for cooling air teaches a supersonicflow separator, wherein a high pressure gas stream is expanded tosupersonic velocity through a supersonic effuser, thereby forming liquidand/or solid particles. The supersonic gas stream is made to traverse aplanar bend provided with a permeable outer wall to and through whichliquid and/or solid particles are inertially moved and thereby separatedfrom the gas stream. While such a device is capable of separatingcomponents from a gas stream, the device may not operate effectively ifthe permeable wall became plugged by debris. As such, this devicerequires a considerable amount of maintenance to maintain itsefficiency.

Another previous device is a refrigeration system comprising a closedloop system that circulates refrigerants. This device teaches placing avortex generator between a compressor and condensers, and the mixedrefrigerants are controlled via a vapor separator, most preferably avortex generator. While such a device provides refrigeration, itutilizes refrigerants fluids, which may include environmentally harmfuland unsafe chemicals, such as chlorofluorocarbons.

Therefore, it is readily apparent that there is a need for an apparatuscapable of separating gases into hot and cold streams utilizing simplecomponents that are easy to repair and replace, and which utilizesmaterials that are environmentally benign.

BRIEF SUMMARY OF THE INVENTION

Briefly described, in a preferred embodiment, the present inventionovercomes the above-mentioned disadvantages and meets the recognizedneed for such an apparatus by providing a kinetic energy heat pump andmethod for heating and cooling air, and more specifically a kineticenergy heat pump comprising a nozzle, a tube and a diffuser having aseparating baffle disposed therewithin, wherein the tube comprises aradial bend, and wherein gases accelerated to near sonic velocity travelaround the radial bend and compress outward to form a thermal gradient.

Accordingly, one advantage of this apparatus is that it heats and coolsair without utilizing a heat exchanger, and thus does not incur problemsassociated with heat exchangers, such as, the temperature differentialacross the exchanger surface, or the utilization of toxic refrigerantsand/or the possibility of refrigerant leakage.

According to its major aspects and broadly stated, the present inventionin its preferred form is a kinetic energy heat pump comprising a tubehaving a radial bend. The radial bend preferably comprises betweenapproximately ninety and one hundred and eighty degrees, but could beless than ninety or more than one hundred and eighty degrees so long asreasonable separation of thermal streams can be accomplished. Thekinetic energy heat pump further comprises a nozzle, a diffuser and twooutputs, wherein the nozzle accelerates gas to near sonic, but subsonic,velocities, and wherein the two outputs comprise a hot gas output and acold gas output.

The kinetic energy heat pump accelerates gases around the radial bendand compresses the gases outward to form a thermal gradient. The thermalgradient is formed by action of centrifugal force on the gases, whereingases that are compressed more have increased temperature, and whereinthe thermal gradient is divided via a separating baffle into a fractionhaving hot gases relative to input temperature and a fraction havingcool gases relative to input temperature.

The kinetic energy heat pump further provides a method of heating andcooling air comprising: obtaining a kinetic energy heat pump having atube with a radial bend, a gas source, a blower, an adjustableseparating baffle and two outputs. Gas is accelerated with the blowerand nozzle combination, wherein the accelerated gas flows around theradial bend and into a diffuser with a baffle that divides the gas intohot and cold streams. The method of heating and cooling air furthercomprises extracting the cold stream from one of the two outputs,extracting the hot stream from the other of the two outputs andadjusting the baffle to select the temperature of the hot and cold gasstreams.

Additionally, the kinetic energy heat pump comprises a blower, a nozzle,a tube having a bend a diffuser and a separating baffle, wherein theblower and nozzle combine to produce near sonic, but subsonic, flowaround the bend in the tube. The kinetic energy heat pump furthercomprises a cold gas fraction and a hot gas fraction, wherein theseparating baffle selectively controls the temperature of gases in thehot and cold gas outlets.

More specifically, the present invention is a kinetic energy heat pumpcomprising a blower, a nozzle, a tube with a bend, a diffuser, aseparating baffle, a cold channel and a hot channel. The blower is influid communication with the nozzle, the nozzle is in fluidcommunication with the tube and the tube is in fluid communication withthe diffuser, wherein the separating baffle is disposed within thediffuser. The diffuser is in fluid communication with the cold channeland the hot channel. As discussed more particularly hereinbelow, theseparating baffle pivots at either end, wherein the baffle isselectively adjusted to modify the quantity of cold gas molecules andhot gas molecules that travel through a cold and a hot channel,respectively, wherein selection of the quantity of molecules selects thetemperature of the gas steams passing through the hot and cold channel.

The blower introduces gas molecules into the kinetic heat energy heatpump, wherein the blower comprises an outlet end that enters the nozzle.The nozzle comprises an inlet, a throat and an outlet, wherein the endof the blower is in fluid communication with the inlet of the nozzle.

The tube comprises a first end, a radial bend and a second end, whereinthe outlet of the nozzle is in fluid communication with the first end ofthe tube. Further, the second end of the tube is in fluid communicationwith the diffuser, wherein the diffuser has a separating baffle disposedtherewithin. Additionally, the end of the diffuser is in fluidcommunication with the cold channel and the hot channel, wherein thecold channel comprises a cold inlet and a cold outlet, and wherein thehot channel comprises a hot inlet and a hot outlet.

In use, the blower introduces the gas molecules into the nozzle, whereinthe nozzle accelerates the gas molecules to near sonic, but subsonic,velocities. The accelerated gas molecules exit the nozzle and enter thefirst end of the tube, traveling into the radial bend, wherein the tubecomprises an outer radius and an inner radius. As the gas moleculestravel around the radial bend, centrifugal force compresses the gasmolecules outwardly against an outer wall of the tube, thereby heatingthe gas molecules. Similarly, the gas molecules expand near the innerwall to form a cold stream of gas molecules, wherein the cold gasmolecules are disposed predominately near an inside wall of the tube.The hot gas molecules and the cold gas molecules travel through thesecond end of the tube and into the diffuser. The hot gas moleculesenter the hot side of the diffuser, wherein the hot side is incommunication with the outer portion of the bending tube, and whereinthe diffuser decelerates the hot gas molecules back to ambientpressures. Similarly, the cold gas molecules enter the cold side of thediffuser, wherein the cold side is in communication with the innerportion of the bending tube, and wherein the diffuser decelerates thecold gas molecules back to ambient pressure. The separating bafflesubsequently separates and directs the hot gas molecules and the coldgas molecules into the hot channel opening and the cold channel opening,respectively. The hot gas molecules subsequently travel through the hotchannel and exit via the hot outlet. Likewise, the cold gas moleculestravel through the cold channel and exit via the cold outlet.

The kinetic energy heat pump may be particularly understood in terms ofthe following equations: Newton's Second Law of Motion states F=ma,wherein F=force, m=mass and a=acceleration. Also, P=F/A, whereinP=pressure, F=force and A=area. Lastly, the acceleration due tocentrifugal force is given as a=v²/r, wherein a=acceleration, v=velocityand r=radius. Solving for F, results in F=PA. Substituting for F,results in ma=PA. Solving for P and substituting for a, results inP=mv²/rA for gaseous fluids.

Additionally, it is assumed that the working fluid is ideal, althoughthe system will work with non-ideal gaseous fluids. Thus, equationsabout ideal gas may be applied, wherein PV=mRT, and wherein P=pressure,V=volume, m=molecular mass, R=ideal gas constant 53.34ft-lb_(f)/lbr_(m)-°K and T=temperature. Solving for T and substitutingfor P, equation T=(V/R) (v²/rA) is obtained, wherein T is a function ofradius r of the tube. Assuming A is constant, taking the derivative of Tand r, the following equation is obtained, T_(o)=[T_(i) ²+v²/R(ln(r_(o))−ln(r_(i)))]^(1/2), wherein T_(o) is the temperature of thegas stream at r_(o), and wherein T_(i) is the temperature of the gasstream at r_(i).

An example of numerical values associated with the kinetic energy heatpump is shown in Example 1. For example, if outer radius of the tube isfour (4) inches and the inner radius of the tube is two (2) inches, andthe gas molecules exit the nozzle at a velocity of approximately 1129ft/sec, then the temperature of hot gas molecules at the outer radius is78.4° F. and the temperature of gas molecules at the inner radius is 75°F.

Additionally, the separating baffle is selectively adjusted via a rodwhich adjusts a pivot point at the inlet side of the baffle to vary thefraction of the hot gas molecules and the cold gas molecules enteringthe hot channel opening and the cold channel opening, respectively,wherein the separating baffle selectively adjusts, thereby increasingthe amount of the hot gas molecules that exit the hot output anddecreasing the amount of the cold gas molecules that exit the coldoutput or, alternatively, decreasing the amount of the hot gas moleculesexiting the hot output and increasing the amount of the cold gasmolecules exiting the cold output. It will be recognized by thoseskilled in the art that the quantity of the hot gas molecules and thecold gas molecules exiting the cold outlet and the hot outlet may beadjusted via any sort of means known in the art for dividing a fluidstream in lieu of the separating baffle with the pivot.

Accordingly, a feature and advantage of the present invention is itsability to heat and/or cool air with greater efficiency thanconventional pump technology because no energy is expended bytransferring heat over and around a heat exchanger.

Another feature and advantage of the present invention is that itcomprises parts that are easy to replace and service.

Still another feature and advantage of the present invention is that itdoes not require environmentally damaging chlorofluorocarbons or otherworking fluids other than the gas utilized in the system, such as air.

Yet another feature and advantage of the present invention is itsability to be utilized for facility HVAC systems.

Yet a further feature and advantage of the present invention is itsability to be utilized for vehicle or aircraft HVAC systems, wherein thevehicle's velocity may replace the blower.

Yet still another feature and advantage of the present invention is itsability to be utilized with any gaseous fluid or mixture of gases.

A further feature and advantage of the present invention is its abilityto be utilized for separation of gases.

These and other features and advantages of the present invention willbecome more apparent to one skilled in the art from the followingdescription and claims when read in light of the accompanying drawings.

Referring to FIGS. 1-2, in use, blower 20 introduces gas molecules 21into nozzle 30, wherein nozzle 30 accelerates gas molecules 21 to nearsonic, but subsonic velocities. Accelerated gas molecules 21 exit nozzle30 and enter first end 41 of tube 40, traveling into radial bend 42,wherein radial bend 42, and wherein tube 40 comprises outer radius r_(o)and inner radius r_(i). Kinetic energy heat pump 10 has been tested atradial bends 42 comprising approximately between ninety and one hundredand eighty degrees. Bends 42 of less than ninety or more than onehundred and eighty degrees could be utilized so long as adequate thermalseparation results.
